I will put up pics of the gun later today. It is an earlier style small ring Mauser with 2 locking lugs and screw retained safety. So based on the proof marks it is a .318 or a .323? Or we can't tell for sure? Like I said, the muzzle diameter seems to suggest .323 diameter.
I was kind if thinking that 1933 was the proof year and I would have thought by that time that the .318 bullet was phased out.
